A total of $86-million has been awarded to three contractors for work on the Gordie Howe International Bridge.
The Windsor-Detroit Bridge Authority and its partners are kicking off phase two of prep work at the plaza.
Work being done includes high voltage cabling and accessories and transmission and distribution line relocation.
Officials with the bridge authority say the site contains overhead lines that need to be relocated. Many of them will be moved underground and some will be connected onto new transmission towers.
The bridge authority says this work will ensure that the plaza will be ready for the private-sector partner chosen to build the Gordie Howe International Bridge project.
Phase 2 activities should be complete in mid-2018.
